Find the axis of symmetry and vertex for the parabola y = –x^-8x+8

y = –x^-8x+8

Answer:

18

Step-by-step explanation:

They want u to find MR, and I can do that by taking CR - CM

But first we need to know what is x

Now u know CM + MR =CR

Therefore

(3x - 2) + (x+8) = 46

3x - 2 + x + 8 = 46

4x + 6 = 46

4x = 40

x = 10

Now we know x is 10, let's just make it easier first

CM = 3x-2

= 3 (10) - 2

= 28

MR = x + 8

= 10 + 8

= 18

Now we got all our values

They want MR?

MR = x + 8

= 10 + 8

= 18

HERE U GO

Answer:

18

Step-by-step explanation:

cm=3x -2

mr=x +8

cr=46

cm+mr=cr

3x-2+x+8=46

4x+6=46

4x=46-6

x=40/4

x=10

hence, mr=x+8

=10+8

=18

Answer:

(1, 8 )

Step-by-step explanation:

A translation of 2 units left means subtracting 2 from the x- coordinate

A translation of 4 units up means adding 4 to the y- coordinate

Z (3, 4 ) → Z' (3 - 2, 4 + 4 ) → Z' (1, 8 )

Cost of 9candies=40-4=36$

Cost of one candy:-

[tex]\\ \sf\longmapsto \dfrac{36}{9}[/tex]

[tex]\\ \sf\longmapsto 4\$[/tex]

Answer:

Let c = the cost of each candy bar

4 + 9c = 40

subtract 4 from 40

9c = 36

divide 9 from 36

c = $4.00

Answer:

n = 11.333

Step-by-step explanation:

I'll take it as your "h" was a typo and u want to find n

31-3n+11 = 8

- 3n = 8 - 11 -31

- 3n = - 34

n = 11.333

31-3n+ 11=8

-3n=8-11-31

-3n=-6

3n=6

n=6/3

n=2

An equation to model the sum of the situation will be +1 - 1 = 0.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that "A hydrogen atom has a zero charge because it has been negatively charged electron and one positively charged proton."

The expression for the given situation will be written as below:-

+1 - 1 = 0

Therefore, the equation to model the sum of the situation will be +1 - 1 = 0.

The perimeter of a triangle is 5.25 inches.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

The perimeter of a triangle = sum of all sides

Two triangles are said to be congruent if their corresponding sides and angles are equal.

Given that an equilateral triangle has three congruent that measure 1 3/4 inches on each side.

⇒ [tex]1\dfrac{3}{4} = \dfrac{3+4}{4} = \dfrac{7}{4}[/tex]

Since the perimeter of a triangle is the addition of the lengths of the triangle's three sides.

So the perimeter of a triangle = sum of all sides

The perimeter of a triangle = 7/4 + 7/4 + 7/4

The perimeter of a triangle = 21/4

The perimeter of a triangle = 5.25

Hence, the perimeter of a triangle is 5.25 inches
